Product Description:

The CSH01.1C-CO-EN1-MEM-MD2-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed in a modular drive stack, it provides the computational layer between higher-level motion commands and the power stage, coordinating servo axes and peripheral devices inside an automation cell. Through integrated fieldbus ports, analog references, and local I/O, the unit can receive command data, supervise feedback hardware, and issue time-critical signals to connected motors and actuators. Because the control section sits above the power electronics, it handles command processing, interface exchange, and feedback tasks within the same drive assembly.

Two differential analog outputs deliver up to 1 mA at a reference level of 5 V, stepped in increments of 19.5 mV/inc; this resolution allows finely graduated velocity or torque setpoints. Native communication is handled over CANopen / DeviceNet, while an auxiliary RS-232 service port supports diagnostic traffic at 115 kBaud. This combination allows the unit to exchange network commands while still providing a direct local service connection. Local expansion is provided by a module with 16 inputs and 16 outputs plus an SSI channel for deterministic position capture from external encoders. The dedicated resolver/HSF interface can accept analog rotor signals, and the control section can then provide absolute SSI or incremental A/B/Z emulation for connected devices.

The encoder rail supplies 8 V to power position transducers. On startup, the board can draw an inrush current of 4 A for up to 100 ms, and steady operation afterward requires only 17.5 W. Low steady-state demand helps limit heat buildup inside the drive stack. Logic inputs accept 24 V at 3 mA, source outputs switch 24 V at 0.5 A, and an onboard relay is rated for DC 24 V at 1 A. The relay output supports interlock signaling, and the logic I/O works with common 24 V control circuits used in multi-axis machinery.
